Detailed explanation-1: -1989: Voyager 2 becomes the first and only spacecraft to visit Neptune, passing about 4, 800 kilometers (2, 983 miles) above the planet’s north pole. 2002: Using improved observing techniques, astronomers discover four new moons orbiting Neptune: Laomedia, Neso, Sao and Halimede.
Detailed explanation-2: -Voyager 2 is the only spacecraft to have visited Neptune. No spacecraft has orbited this distant planet to study it at length and up close.
Detailed explanation-3: -Following its flybys of Jupiter and Saturn, Voyager 2 became the first spacecraft to visit Uranus. Voyager 2 remains the only spacecraft to have flown by Uranus. The planet appeared to have few features but Voyager 2 found evidence of an ocean of boiling water about 500 miles (800 kilometers) below its cloud tops.
Detailed explanation-4: -Space probes contain instruments to collect data and travel out of Earth’s orbit to explore places that would be too dangerous for astronomers; the instruments that a probe contains depends upon the space mission.
Detailed explanation-5: -Launched 16 days after its twin Voyager 2, Voyager 1 has been operating for 45 years, 7 months and 3 days as of April 9, 2023 UTC [refresh]. It communicates through NASA’s Deep Space Network to receive routine commands and to transmit data to Earth. Real-time distance and velocity data is provided by NASA and JPL.
Detailed explanation-6: -A probe is a spacecraft that travels through space to collect science information. Probes do not have astronauts. Probes send data back to Earth for scientists to study.
